Sheer force

When they first see the crystal onix Kai Ming is amazed how something like this exists but he get a wake up call that he still in battle with a wild pokemon when onix use a rock throw

Ralts use telport to get then further back from onix while he calls out treecko and darmanitan Kai Ming decided to rotate his team for this battle as rookiedee and pidgeot would be the best option for this battle

While treecko fires bullets seeds and darmanitan goes in to with a fire punch it affect the crystal onix but it keep up with it assault

Time pass as they continue to keep up the attack while they have figured out fire has effect on the crystal onix so Kai Ming has ralts to charge up fire energy for mystic fire while duskskull generates psychic energy for imprison so their combined their flame prison would be even stronger

While they are doing that treecko for the past while has been facing off the crystal onix with darmanitan taking most of the hit while he follows up with bullet seed but as time past treecko energy active as he is overflowing with grass type energy to point where treecko has comprehend seed bomb

The crystal onix roar as it is being burned while taking on seed bombs

Once a few more minutes past as flame prison was released the crystal onix body looked like it was melting as they had not heard the cry of the crystal onix Kai Ming had thought he had defeat it but soon a shiny glow blow past then and they see the crystal onix body return to normal
